16v205 9 Posted May 31, 2007 Hi Ive had a look around but cant find the info needed. Ive heard that the xu9 diesel cranks are the same as the mi16 cranks but looking on the pug catalogue they are a different part number. Does anyone know for sure if there the same? Would it be a suitable replacement for a 88mm mi16 crank? and will it fit the block without any castings/spraybars etc getting in the way? Cheers Rich Share this post Link to post Share on other sites
16v205 9 Posted June 1, 2007 No one any ideas or seen/measured one? Share this post Link to post Share on other sites
Baz 421 Posted June 2, 2007 I'd be quite interested to know too, being a lot easier to get hold of. Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted June 3, 2007 They have differnt partnumbers for reasons unknown to me. But they are definately the same item. Same sizes and double webbing. Share this post Link to post Share on other sites
Baz 421 Posted June 3, 2007 Excellent. I'll find some time soon to take one out. Cheers Hilgie. Share this post Link to post Share on other sites
smighall 1 Posted June 3, 2007 I think they only have 4 counterbalance weights as opposed to 8 on the mi cranks? Share this post Link to post Share on other sites
Baz 421 Posted June 3, 2007 I've been donated a couple of 1.9TD lumps so will take one out and compare them with an Mi crank just to be sure. Share this post Link to post Share on other sites
16v205 9 Posted June 3, 2007 I think they only have 4 counterbalance weights as opposed to 8 on the mi cranks? Id heard something about the balance weights before but was unsure. I dont know how only having 4 balance weights would really affect the reliability of the crank assuming its only going to do 7500rpm max. It'd be nice to know one way or the other if the diesel cranks are usable as then well have loads of easy spares for our mi's when they spin a shell Rich Share this post Link to post Share on other sites

RossD 43 Posted June 6, 2007 The diesel crank does not clear the oil sprays on the block of the MI So the counterbalance weights are bigger? Share this post Link to post Share on other sites
Kev-G 1 Posted June 6, 2007 So the counterbalance weights are bigger? Counterweights are straight and don't feature the chambfer to clear the oil spays on the Mi. Share this post Link to post Share on other sites
Baz 421 Posted June 7, 2007 Haven't actually removed one yet, but took some pictures of one still in situ, will hopefully give enough to compare; And an Mi crank for reference; HTH! Looks to me as if the diesel item doesn't have the same webbing/counterbalances as the Mi item, and from what's been said perhaps not ideal for the spray bars, although it looks as if the chamferring is present on the diesel one as the Mi one? (If i'm thinkinh/looking at the same parts on the crank meant above anyway! ) Any thoughts? Share this post Link to post Share on other sites
DrSarty 90 1 Cars Posted June 7, 2007 (edited) The diesel crank does not clear the oil sprays on the block of the MI Well my XU11D crank (from a 'P' or 'R' plate 2.1TD 406), which is a 92mm crank, dropped straight in to my (iron) S16 block and span without fouling. See my thread - Matt of QEP did comment on this; he seemed quite surprised. And Baz - your piccy links are FUBAR'd!

That's only got single counterweights therefore is equivalent to an 8v crank....It would certainly fit an Mi, but wouldn't be desired. 1.9 and 2.0 Mi's feature different sprays - 1.9 are 'bars' with go front to back, across the cylinder. 2.0 are smaller 'jets' if you like which sit to one side.

JERAM 0 Posted June 7, 2007 Well my XU11D crank (from a 'P' or 'R' plate 2.1TD 406), which is a 92mm crank, dropped straight in to my (iron) S16 block and span without fouling. See my thread - Matt of QEP did comment on this; he seemed quite surprised. And Baz - your piccy links are FUBAR'd! Rich mmm, a diesel crank will not fit a alloy block with oil sprays. it will fit a iron 2.0ltr MI block. i thought we were talking about a 1.9 MI 88mm Share this post Link to post Share on other sites
16v205 9 Posted June 7, 2007 So were saying a diesel crank will fit the iron block as the spray bars are different but wont fit a alloy mi block. Is there a good reason not to use the 88mm diesel crank assuming its the one with 8 balance weights? Is it heavier or does it have different sizes journals?

Rich I thought it was only the 1.9 turbodiesel cranks that had the 8 counterweights, while normal 1.9D engines just have 4 counterweights. The 2.1 crank is one different story anyway, it's a forged item while the others are cast afaik. Share this post Link to post Share on other sites

petert 554 Posted June 7, 2007 (edited) The 2.1 crank is one different story anyway, it's a forged item while the others are cast afaik. I must inquire how much a new one costs. Diesels are so rare over here, that they attract premium prices at the wreckers. Edited June 7, 2007 by petert Share this post Link to post Share on other sites
RossD 43 Posted June 7, 2007 I must inquire how much a new one costs. Diesels are so rare over here, that they attract premium prices at the wreckers. From the dealer, inc VAT, a 2.1TD crank is...... £1141.98 retail. Might be able to get some discount if you are in the trade or owners club etc. (The joys of having access to Citroen parts price list ) Share this post Link to post Share on other sites
